MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a Microsoft Office document containing VBA macros. The 'Document_Open' macro is configured to auto-execute, and heuristics indicate a 'CreateObject' call, suggesting the execution of code. ClamAV detection as 'Doc.Downloader.Generic' further supports the malicious nature. The presence of the 'macros.bas' file and the auto-execution of VBA code strongly indicate a downloader pattern, likely intended to fetch and run a second-stage payload.

Heuristics 7

ClamAV detected this file as malware: Doc.Downloader.Generic-9785156-0
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
